Abstract
L'invention concerne un procédé pour la post-réticulation en surface de polymères hydroabsorbants par traitement de ces derniers avec une solution permettant la post-réticulation en surface. Pendant ou après l'aspersion, les polymères subissent une post-réticulation et sont séchés par élévation de la température à une valeur comprise entre 50 et 250 ·C, et l'agent de réticulation renferme un ester de l'acide borique avec un alcool bivalent ou trivalent dissous dans un solvant inerte. L'invention concerne également des polymères hydroabsorbants s'obtenant selon le procédé précité, ainsi que leur utilisation dans des articles d'hygiène, des matériaux d'emballage et des non-tissés.
